Image Representation Based on Multi-Scale Edge Compensation - Xue, Wu (1999) (1 citation) (Correct)
....Two classes of methods are provided; one is based upon image segmentation, the other is upon directional decomposition. We consider the idea expressed by the second generation image compression algorithm is in advance for its time, and it is still worthy today. Let us mention synthetic high method [8] here, the idea of which is much more simple but equally significant. 1.3.2 Multi Scale Zero Crossing Representation in Computer Vision That zero crossing position of a Laplacian of Gaussian filtered image corresponds to the image edge is an important viewpoint of D. Marr [9] which evolved into ....

The Laplacian Pyramid as a Compact Image Code - Burt, Adelson (1983) (431 citations) (Correct)
....more quantization levels must be used at high pyramid levels than at low levels. Fortunately, these pixels contribute little to the overall bit rate for the image, due to their low sample density. The low level (high frequency) pixels, which are densely sampled, can be coarsely quantized (cf. 6] [11], 12] RESULTS The final result of encoding, quantization, and reconstruction are shown in Fig. 8. The original Lady image i s shown in Fig. 8(a) the encoded version, at 1.58 bits pixel, is shown in Fig. 8(b) We assume that variable length code words are used to take advantage of the ....
